How To Add Polygon to MetaMask — A Step-by-Step Guide (2024)

MetaMask is a popular cryptocurrency wallet that allows users to securely store, manage, and interact with Ethereum and other Ethereum-compatible cryptocurrencies. The wallet is available as a browser extension for Google Chrome, Firefox, and other browsers. One of the key features of MetaMask is its ability to interact with different networks, such as the Ethereum network, Binance Smart Chain and more.

Recently, the Polygon network has gained significant popularity due to its low transaction fees, fast confirmation times, and interoperability with other blockchains. Within this article, we will provide a step-by-step guide on how to add Polygon to MetaMask and explain the benefits of using the network on MetaMask. By the end of this guide, you will have a complete understanding of how to use the Polygon network on MetaMask and be able to take advantage of its features.

Understanding Polygon Network

The Polygon network, previously known as the Matic network, is a Layer 2 scaling solution for Ethereum. It is a framework for building and connecting Ethereum-compatible blockchain networks. The Polygon network aims to provide fast and cheap transactions while maintaining interoperability with the Ethereum network.

Advantages of using the Polygon network

One of the main advantages of using the Polygon network is its fast confirmation times and low transaction fees. The network achieves this thanks to its Proof of Stake (PoS) consensus algorithm, reducing the computational requirements needed to validate transactions. This means transactions can be processed faster and at a lower cost compared to the Ethereum network.

Another advantage of using the Polygon network is its interoperability with other blockchains. For example, the network supports the Ethereum Virtual Machine (EVM), which allows for compatibility with Ethereum-based dApps and smart contracts. Additionally, the network supports interoperability with networks such as Binance Smart Chain, making it easier for users to move their assets between different networks.

How the Polygon Network Differs From Other Networks

The Polygon network differs from other networks in several ways. Unlike other scaling solutions, such as sidechains, which require users to move their assets to a different network, the Polygon network allows users to keep their assets on the Ethereum network while still benefiting from the faster and cheaper transactions on the Polygon network.

Furthermore, the Polygon network uses a unique approach to achieve its fast transaction speeds and low fees. Instead of creating a separate network, the Polygon network is a framework that allows for the creation of multiple interconnected networks. As a result, different networks can be created for specific use cases, such as gaming or DeFi, while maintaining interoperability.

Is Polygon Wallet Address the Same As MetaMask?

Yes, a Polygon wallet address is the same as a MetaMask wallet address when using the Polygon network on MetaMask. This is because MetaMask is a wallet that allows users to interact with different networks, including the Polygon network. When using MetaMask to interact with the Polygon network, you will have a Polygon wallet address linked to your MetaMask wallet.

This means you can use the same MetaMask wallet address to send and receive transactions on the Polygon network as you would on other networks supported by MetaMask. However, it is important to note that the wallet address may differ if you use a different wallet to interact with the Polygon network.

What Is the URL for Polygon Mainnet?

The URL for the Polygon mainnet is https://polygon-rpc.com/. This is the Remote Procedure Call (RPC) endpoint for the Polygon network’s mainnet. Developers and users can use this endpoint to connect to the Polygon network, interact with decentralized applications (dApps), send and receive transactions, and more.

When adding the Polygon network to a wallet or other application, you may be asked to enter this URL to connect to the network. It is important to note that this URL is specific to the Polygon mainnet and may be different for other networks or testnets.

What Is Polygon Mainnet?

Polygon mainnet is the production-ready version of the Polygon network, a Layer 2 scaling solution for Ethereum. The mainnet is the live version of the network that is open to the public and used for real-world transactions and interactions with decentralized applications (dApps) and smart contracts.

The mainnet uses a Proof of Stake (PoS) consensus algorithm, which reduces the computational requirements needed to validate transactions, resulting in faster and cheaper transactions.
